Roads API toma hasta 100 coordenadas independientes y muestra el segmento de ruta más cercano para cada punto. No es necesario que los puntos pasados sean parte de una ruta continua.

Si estás trabajando con puntos de GPS secuenciales, utiliza Snap to Roads.

Requests

Una solicitud a las rutas más cercanas se debe enviar a través de HTTPS y toma la siguiente forma:

https://roads.googleapis.com/v1/nearestRoads?parameters&key=YOUR_API_KEY

Required parameters

  • points

    The points to be snapped. The points parameter accepts a list of latitude/longitude pairs. Separate latitude and longitude values with commas. Separate coordinates with the pipe character: "|". For example: points=60.170880,24.942795|60.170879,24.942796|60.170877,24.942796.

En la respuesta, se usa el siguiente esquema.

NearestRoadsResponse

FieldRequiredTypeDescription
optional Array<SnappedPoint>

An array of snapped points. Sometimes containing several snapped points for the same point with differing placeId or location.

See SnappedPoint for more information.

SnappedPoint

FieldRequiredTypeDescription
requiredLatitudeLongitudeLiteral See LatitudeLongitudeLiteral for more information.
requiredstring

A unique identifier for a place. All place IDs returned by the Roads API correspond to road segments.

optionalnumber

An integer that indicates the corresponding value in the original request. Each value in the request should map to a snapped value in the response. However, if you've set interpolate=true or if you're using nearest roads, then it's possible that the response will contain more coordinates than the request. Interpolated values will not have an originalIndex. These values are indexed from 0, so a point with an originalIndex of 4 will be the snapped value of the 5th latitude/longitude passed to the path parameter. Nearest Roads points may contain several points for single coordinates with differing location or placeId.

LatitudeLongitudeLiteral

FieldRequiredTypeDescription
requirednumber

Latitude in decimal degrees
